Title
(EN) TECHNIQUES FOR REAL-TIME MAPPING IN A MOVABLE OBJECT ENVIRONMENT
(FR) TECHNIQUES DE CARTOGRAPHIE EN TEMPS RÉEL DANS UN ENVIRONNEMENT D'OBJET MOBILE
Abstract
(EN)
Techniques are disclosed for real-time mapping in a movable object environment. A real-time mapping system can include at least one movable object including a computing device, a scanning sensor electronically coupled to the computing device, and a positioning sensor electronically coupled to the computing device. The computing device can include at least one processor and a mapping manager, the mapping manager may be configured to obtain mapping data from the scanning sensor and obtain positioning data from the positioning sensor. The mapping manager can associate the mapping data with the positioning data based at least on time data associated with the mapping data and the positioning data, and then generate a map in a first coordinate system based at least on the associated mapping data and positioning data.

L'invention concerne des techniques de cartographie en temps réel dans un environnement d'objet mobile. Un système de cartographie en temps réel peut comprendre au moins un objet mobile comprenant un dispositif informatique, un capteur à balayage couplé électroniquement au dispositif informatique et un capteur de positionnement couplé électroniquement au dispositif informatique. Le dispositif informatique peut comprendre au moins un processeur et un gestionnaire de cartographie, le gestionnaire de cartographie peut être conçu pour obtenir des données cartographiques en provenance du capteur à balayage et obtenir des données de positionnement en provenance du capteur de positionnement. Le gestionnaire de cartographie peut associer les données cartographiques aux données de positionnement en fonction au moins de données temporelles associées aux données cartographiques et aux données de positionnement, puis générer une carte dans un premier système de coordonnées en fonction au moins des données cartographiques et des données de positionnement associées.
